Sanding!! I hate stinking sanding!!![:@] My new shop is too small and my planes are stored in it so I have to sand outside with the parts on my lap. I'm filling and sanding A wing at the moment. Don't you just love it when it slides off your lap and you feel and hear the ribs breaking. [&:]
I have given it A couple of days off and will get back to it when I'm in the mood and the weather clears up A bit. Sanding outside in the wind doesn't help at all.
Just relax and go find something else to do for A while, the plane will be there when you feel like working on it again.
